Webb actually concludes that there are no extraterrestrial civilizations (ETCs) in the galaxy -- a result, I think, of taking the Fermi paradox too seriously and the Copernican principle not seriously enough. Richard Gott's doomsday argument comes up in Solution 27. I, perversely, kind of like one of the variants of Solution 23: Every smart ETC is keeping its head down, suspecting that the galaxy is a rough neighborhood and that some predator race will annihilate them if they make their existence known. no reviews | add a review
Amazon.com Product Description (ISBN 0387955011, Hardcover)FROM THE REVIEWS: ¿Webb offers coherent, understandable, and sometimes humorous coverage of a diverse range of topics. He provides readers with non-trivial insights into research fields they may not have encountered previously . . . I think everyone who has ever considered the possibility that other intelligent civilizations exist elsewhere within our galaxy will enjoy Where Is Everybody? They will find much to agree with, and much to argue about, in this very accessible volume.¿ ¿SCIENCE During a Los Alamos lunchtime conversation that took place more than 50 years ago, four world-class scientists agreed, given the size and age of the Universe, that advanced extraterrestrial civilizations simply had to exist. The sheer numbers demanded it. But one of the four, the renowned physicist and back-of-the-envelope calculator Enrico Fermi, asked the telling question: If the extraterrestrial life proposition is true, he wondered, "Where IS everybody?" In this lively and thought-provoking book, Stephen Webb presents a detailed discussion of the 50 most cogent and intriguing answers to Fermi's famous question, divided into three distinct groups: - Aliens are already here among us. Here are answers ranging from Leo Szilard's suggestion that they are already here, and we know them as Hungarians, to the theorists who claim that aliens built Stonehenge and the Easter Island statues. - Aliens exist, but have not yet communicated. The theories in this camp range widely, from those who believe we simply don't have the technologies to receive their signals, to those who believe the enormities of space and time work against communication, to those who believe they're hiding from us. - Aliens do not exist. Here are the doubters' arguments, from the Rare Earth theory to the author's own closely argued and cogently stated skepticism. The proposed solutions run the gamut from the crackpot to the highly serious, but all deserve our consideration. The varieties of arguments -- from first-rate scientists, philosophers and historians, and science fiction authors -- turn out to be astonishing, entertaining, and vigorous intellectual exercises for any reader interested in science and the sheer pleasure of speculative thinking. Stephen Webb is a physicist working at the Open University in England and the author of Measuring the Universe.(retrieved from Amazon Fri, 24 Apr 2009 07:58:23 -0400) The first test round has been closed.

Well, there are plenty of good explanations, as this book proves. The solutions are divided in three categories: "they're already here," "they exist but we can't communicate with them," and "we're alone". Since there's a real lack of proper knowledge about these things, reader will find plenty of educated guesses, hazy probabilities and that sort of thinking, but that's the nature of the whole question.
I'd definitely recommend this book to anybody who's interested in the existence or non-existence of extraterrestrial life. While there are no set answers, this book will give the reader a lot of material to chew on. (Review based on the Finnish translation.)
